With the latest release of Sesam HydroD software for floating structures, DNV GL is now offering a completely new and pioneering stability analysis solution that allows for hydrodynamic and stability analysis on one common model, giving naval and offshore engineers unprecedented control over their projects.

The design and engineering of floating structures relies heavily on both hydrodynamic and stability analyses, which are necessary in order to optimise safety in various environmental conditions. These two types of analyses have usually been performed with separate models and software system. This common way of working actually causes inefficiencies and raises the cost of the design process, possibly leading to errors or inaccuracies during the analyses.

DNV GL has now launched the new Sesam HydroD version 5, making it possible for naval architects and offshore engineers to run a stability analysis in a user-friendly interface, on the same model that they are using for hydrodynamic analysis. Sesam HydroD 5 empowers them to save time and cost, reduce errors, and also gives them unparalleled oversight over their data with a powerful solver and many options that increase flexibility and control with tailored solutions.

“This is a huge step forward for Sesam,” says DNV GL – Software CEO, Are Føllesdal Tjønn. “It is the first release of Sesam HydroD on our new software platform. This will improve the user experience and the efficiency of analysis,” he says.

The new platform provides users with an enhanced and easy-to-use interface, report generation in an editable Word format. Reusable and tailored templates will simplify design approval process for stability analysis with relevant authorities. It supports all main rule sets for intact and damaged stability, including IMO, DNV GL, ABS, MARPOL and NMA rules.

“This is an important milestone in the development of Sesam HydroD,” says Torgeir Vada, Product Manager Floating Structures at DNV GL - Software. “We have a very strong offering that will help our users perform stability analyses much more accurately and efficiently and give them unparalleled oversight of their projects,” he says.
